device/device_util: Add string for DEVICE_PATH_NONE

Add string for DEVICE_PATH_NONE in dev_path.
The enum DEVICE_PATH_NONE can be translated to string and should not
be translated by "Unknown device path type: 0".

Makes console output a lot prettier and readable.

Note: DEVICE_PATH_NONE is used as dummy devices for hotplugable slots.
